I've never understood why you'd want a bypass switch inside the device you want to bypass, but this one actually makes sense - just flip the switch, pull the whole AC input module out of the broken unit, plug in the replacement and turn it back to UPS. Nice.
Hi. I need a little help. I have a similar UPS MGE EX11RT 220V 1 phase. But I don't have a wire connection unit with a bypass switch. I can't use UPS because of this problem. I would like to ask you to send an electrical diagram of the internal connections. I cannot understand the purpose of the internal 5 pairs of contacts - which of them are N and L of the bypass , which are N and L of the external 220V network and which are N and L of the output voltage to the load. It is also unclear what the purpose of the contacts of the small lower connector with 6 contacts is. It looks like it is needed to determine the bypass connection and start UPS. I need the wiring diagrams or the external unit itself. Thank you in advance.
It really has to have 20+ kW rating written on it before I expect to find some useful bricks. Up to 20 kW you can still risk that its just TO-247 or Skiip modules :(
This device can run in Line Interactive (ECO) mode and Online mode where input is powering inverter continuously so the output is always clean. It is great device not deserving to be a donor. It can be powered by PV microinverters to provide clean power and in case of batteries drain bypassed to electric company.
You point out a important feature here, that is important in industrial settings, that UPS is not just for backup power. It also gets rid of all harmonic noise, switching transients, voltage sags and swells. It will keep your main 10kV/400V transformers happy from limiting the harmonic noise that could overload your transformer, even if you are far from its rated load current.
nice sir, well u guide me for my mge ups system,its not working on battery power while its charging the batteries,so teach me how i can repair my inverter part,thanx.
Smaller board looks like two phase pfc to me, probably used when charging. Two transformers can acctually be inductors for pfc. Think that you conected it wrong for test. Expect you to demant me in next video. Great job.
I got the board just next to me. Electrolytic capacitors are in parallel and only 450VDC, so if its two phase it would not be 400VAC between phases, but I know where in Denmark it comes from, so it was fed with 3x400VAC+N. The transformers primaries are connected in parallel to a half-bridge of 47N60 IGBTs and the outputs are parallel as well. But enough about that, I will make a video about it :)
@@KaizerPowerElectronicsDk l chose bit wrong wording. Single input phase is converted into DC by two inductors sharing the current. It is called interleaved power factor correction. There are nice application notes with pictures how tranzistors and inductors are arranged. Sometimes are called two phase because tranzistors are switched interchangeably.

My team work has finished installing 555 unit UPS EATON 6KVA model 9E6Ki. Thank the God everything is done.
Know anything about the eaton 5p UPS and know how to get it back into boot loader mode from a failed firmware? Unit dead wont turn on :( Used to
5:28 I think it mostly for replace faulty unit without cuting the load, pretty smart solution.
I hope it only fails with mains voltage present then :)
Would be nice to see how heat dissipation looks in this box under a thermo-vision camera
A bit too late for me to do that test :)
Nice old inverter. The heatsink with the 4-5 paalel IGBT are in halfbridge connectio. On the ther heatsink...I cannot understand.
Nice explained.thanks you.

I do not have any wiring diagrams. Contact EATON.
Nice teardown, I was pretty surprised that there are only TO-247 devices and no IGBT bricks.
Definately a lot of useful parts to be salvaged. :)

Shank's.
May be very good if You SHOW PRINCIPIAL SHEMATIC.
I will remember to include schematics if they are available.

Herr Kaiser, how familiar are you with motor drives, VFDs, and designing inverters for appliances?
As familiar as you can see from my projects on www.kaizerpowerelectronics.dk
Hello.have you a diagram this ups ?
No
@@KaizerPowerElectronicsDk plz send your whatsup number
I have eaton 7 rt ups.but that ups is deth.on power on.plz help me repair the ups

Why does everybody have access to lovely dumpsters
Not dumpsters, metal recycling companies or privately owned metal scrap yards.
87kg toroid sounds awesome!
I should have snapped some pictures of it :(
But that was just impossible for me to get out of the container it was in.
@@KaizerPowerElectronicsDk Based on the success of your other hauls, I blame it on 40 days' mains isolation.
So...you found this in a dumster?
Not dumpsters, metal recycling companies or privately owned metal scrap yards.
@@KaizerPowerElectronicsDk ah, nice.
New version 2019 is very downsized
something stick down on your nose.. 😁
